Model Code and Configuration
| Complete model |
HRP-100-48 |
| Series |
HRP-100: single-output AC/DC power supply with active PFC. The series power number is not this model's guaranteed output wattage. |
| Output-voltage code |
48: nominal 48 V main output. |
| Model-specific rating |
105.6 W at 48 V and 2.2 A; use the individual rating rather than the series number. |
| Configuration boundary |
No additional option suffix is present in this SKU. Optional protection must be confirmed as fitted; a feature from another HRP/HRPG power class is not implied. |

| PFC and inrush limiting |
Built-in active PFC and active inrush-current limiting (block diagram) |
| No-load power consumption |
<0.5 W, as listed for this series |
| Capacitor feature |
The series feature list specifies 105°C long-life electrolytic capacitors; this is not an ambient operating-temperature rating. |
Protection
| Short circuit / overload |
105% to 135% of rated output power. Constant-current limiting is specified for output voltage from 50% to 100% of rated voltage; automatic recovery after the fault is removed. No additional below-50% behavior is stated here. |
| Over-voltage trip range |
57.6 to 67.2 V |
| Over-voltage recovery |
Output shuts down; remove and restore input power to recover. |
| Over-temperature protection |
Optional, not assumed fitted to this unsuffixed SKU. When fitted, output shuts down and recovers automatically after temperature falls. |
An operating-temperature range does not confirm that optional over-temperature protection has been fitted.

No remote-sense terminals, standby output, DC-OK output or active current-sharing terminals are specified for this model in these pages.
Environment and Derating
| Cooling |
Free-air convection; fanless, 1U low-profile construction |
| Working ambient temperature |
-40 to 60 °C; use the derating conditions below |
| Working humidity |
20% to 90% RH, non-condensing |
| Storage temperature / humidity |
-40 to 85 °C; 10% to 95% RH |
| Temperature coefficient |

Unless otherwise stated, parameters are measured at 230 VAC input, rated load and 25°C ambient.
Keep the thermal and input-voltage derating limits together; the nominal output rating does not override either curve.
